The point being that, as far as I have studied this, EVERYONE can be linked to her genetically.
If you have something that contradicts this, I would love to take a look at it.
As for 200,000 years, that is ''speculation'' based on genetic mutation. Unprovable.
Everyone who is currently ALIVE can be linked to her (and she is hypothetical). Not everyone who has ever lived. There is a difference. ME can change hands based on extinction of groups of people. When the current ME (the definition of ME is that she is the MOST CURRENT common ancester through the matrinal line) was alive, she was not the ME. When she was alive, one of her ancestors would have been the ME.
You cannot build a family tree that only links back to her as a lone women mating with a lone man unless you can trace the genetics of the male side of this equation back to a lone man of the same time(unless Adam sinned with another women - this is why we don't have to go back as far for y-chomosome adam, males would mate with more than one woman)
It is also possible that the hypotetical eve would could change hands in the future based on populations dieing out. Based on the mathematics that are used to determine when the hypothetical eve lived, it is also possible that in the future, these mathematics will point to someone else (possibly someone who is alive today).
The ME theory also makes an assumption that mitochondrial dna can only come from the maternal side of the equation. Recent studies have shown that this may not be the case.
There are also studies of X-Chromosome Eve (different dna than mitochondrial dna) that point to a different hypothetical ancestor of a different time than mictochondrial eve. This is why it is important to understand that ME, Y-chromosome adam, and X-chromosome eve only point to the MOST RECENT ancestor of those LIVING today. If this was a lone, common set of ancestors, all 3 of these studies of DNA would point to the same time, expecially mitochondrial eve and X-Chromosome eve. This is not the case.
